If you don't like something about the way your group is being run, a good first step is to discuss your thoughts with the organizer. Some organizers love to get suggestions from members and might make some changes right away. Sharing your thoughts with the organizer (in a respectful way) is definitely the first step.
However, it's up to the organizer to decide how their group is run. If an organizer doesn't take your suggestions, don't feel bad! It just means that they might have a different style than you do.
If you're not able to resolve your differences, then you can always search for another group, or choose to start your own. That way you can organize it in the way that you think is best.
